Some horrible accident might happen to delay us here thirty minutes.

But where the material and the moral exist together, what is to happen then?

If you happen to know several, now is the time to tell them.

If you happen to be unacquainted with its authentic history, so much the better.

But of this we may be sure, that it will not happen again very often.

It is less likely to happen again for the very reason that it has happened.

I am not so presumptuous as to say that for me this may not happen.

I happen to know one of our number who can write a very enviable hand.

More things can happen to a fellow than I ever knew there was!

Brother, you'll be the cause that some misfortune will happen here.
